Specification of Letters Patent.

1917. v Serial'No. 143,614.

Be it known that I, ALFONSO CoR'rELL, a subject of the King of Italy, and a resident of Philadel hia, county of Philadelphia, and State of ennsylvania, have invented an Improvement in TalkingfMachines,of which the following description, in connection with the accompanying drawings, .isa specication, like characters on the drawmgs representing like parts.

This inventlon relates to sound reproducing machines' and -aims to provide a novel machine of this type adapted for playing a ,plurality of records 'successively and 1n repeated-cycles, whereby the records may be played without interruption, `thus making -possible a. reproduction of any desired length.

"My invention comprehends a talking machine having a plurality of preferably continuously operative record carrying members, and automatic means for throwing these record carrying members into operationsuccessively and,.as stated, .in repeated c 7cles.

"Divided and `this application inea January 22,

sively' locking and unlocking the records to their respective turntables.

Referring now to Figs. 1-3, my novel talking machinev is shown as comprising a suitable table orfstand 1, conveniently sup-I ported, as by' hollow legs Q-adapted to 'receive therein sliding rods 3, which may be adjustably locked Vthereto by means of set screws l so that vthe table may be adjusted to any height to suit varying conditions, as de-'` sired.

Mounted on the table able points, are a plurality,`herein two, of turntable supports or frames 5, 5, which may be securedto the table in any 'conven- `ient manner as by bolts 6. The top member 7 of eachl frame, and also the bottom member 8 are each drilled vertically' to provide bearings for the hollow turntable shaft '9 which rotates therein. Each shaft 9 may be,

-if desired, provided with roller bearings 10,

shown here of conventionalform.A

AdJacent the shaft 9, 9, and herein ini. the

rarof the same, Figs. 1, 2, and 3..,is located a driving shaft 11 and provided with a pulf ley 12, by means of which power: may be 1, Figs. '1, 2, ai suit'-l transmitted to said shaft froimany kconvenv ient source, as a motor 12, for instance, beneath the table 1. The shaft 11, see-d11 ig. 2, is provided with a ,plurality .of gears 13,13, each in mesh with a gear 14 on one of the shafts 9, whereby rotation is imparted to the turntables 15, 15, mounted on the upper ends of said shafts.

The turntables 15, 15, are both adapted to be, and preferably are, always in rotation with the shaft 11, as will be more fully described later, and I term them for convenience, simultaneously operative record-carrying members. The records 16, 16, are adapted to be held secured to their respective suc- *'cessively operative record supports or carrynormally Afreely rotatable therein and extending above and below the same,and provided on its upper-end with a nut 18 for locking the record between the same and a ring or shoulder 19 on ,the pintle 17.

The upper end of each shaft. 9 is provided, Fig. 7 with a shoulder 9, for receiving the turntable thereon and said upper end is counter-bored and provided with a crown gear 20 while each ring 19 is provided with a single depending tooth 21, Fig. 7, adapted to engage the teeth of the crown gear 20 when its record is in operation.

For both unlocking the successively operative record carrying member 17 fromthe turntable and its shaft, and for supporting the same while in unlocked or inoperative position, I have provided the following novel construction. .I ust below the lower end of each shaft 9, Figs. 1, 3, is a pintle and record supporting member 22, which normally supports the lower end of the pintie, when in inoperative position with its tooth 21 raised above and out of engage`- ment with the crown teeth 20, as at the right-hand end of Fig. 1. This member 22, when the piutle is in operative position, however, as at the left. Fig. 1, is dropped somewhat below the end of the pinle, permitting the latter to drop down in the shaft 9 and the tooth 21 to engage the crown teeth 20, Fig. 7, and lock the record 1G to its turntable 15 and shaft 9. and to cause it to' rotate wilth said turntable and shaft.

As previously stated the two turntables are so connected with the operating shaft 11 that they are both always in operation but I 1nave provided novel record-shifting means, including the pintle supports 2:2, 22, just referred to, for alternately throwing the pin tles and the records secured thereto into operation and this record shifting means I wid now describe.

It is obvious that it is particularly desirable that means be provided that will Vshift the records so quickly that no noticeable interruption in the reproduction thereof will occur. At any suitable. point, therefore. between the two turntables, and preferably substantially midway thereof, is provided asupport 23 on the table 1, for the 4record shifting lever or walking beam 24, which is pivoted thereto by a pin 25.

This support 23 is, in this case` Fig. 6, an angle iron having a base 23a and rear upturned member 23b provided with lever guides 23a. The lever 24 is preferably a long thin member provided at. suitable points thereon, as at each end, with pintle supports 22, 22. previously referred to, and secured thereto as desired, as by screws 26, Fig. 5.

Itwill be noted from the construction so far described that necessarily when one endot the lever 24 with its corresponding pintle support is depressed, the opposite end, with its corresponding pintle support and pintle, is raised, so that necessarily one pintle with its record is locked to its shaft 9 while theopposite pintle and its record is unlocked from its shaft- 9.

The controlling means for the shifting mechanism, herein comprises, Figs. 3, 4, G, bellerank locking and unlocking levers 2i", pivoted to suitable supports 23b on the table 1, the short arm of each lever bent or otherwise adapted to engage a catch 28, on the rear face of the lever 2l.

The long arm of the lever 27 is extended to form a cam surface 29 adapted to be engaged by a .lever tripping member 30, see Fig. 2, in dotted lines, depending from and adapted to be actuated by the sound arm, and to be more fully described presently. These levers 27 are each normally retained in locking position by means of a leaf spring 31, one end of which is secured thereto, while the opposite end is seated upon the table 1.

For depressing and locking one end of the lever 2l instantly upon the unlocking and raising of the opposite end of said lever, and thus instantly shifting the records, I have invented the following novel mechanism, forming also part of the shifting lever controlling means.

Cn the front face of the lever 24, sec Figs. 3, 4, 5, near each end, is secured a bracket 32, and to the bracket are pivoted rearwardly extending lever positioning members 33, These lever positioning members, see Fig. al, are somewhat.- narrower at their rear ends than at their forward ends, and each has pivoted thereto on its upper face and substantially parallel therewith, a yicldi ingly mounted catch 3l provided with a slot on one edge thereof to engage a pin 3G on the lever positioning member 33 beneath. Each catch is normally held in that position by a leaf spring 37 thereon bearing against Y a pin 38 also extended upwardly from the upper face of the member 33, and acting as a. stop on that side of the member 34. for the same.

Positioned between said members 33, 33, and on the support 23b are pivoted two upright reversing levers 39, 39, each suitably positioned to be engaged bv one of the trip members 30, 30, already referred to, inlinedia-tely after the member 30. in its travel laterally depresses the cam end of one of the locking levers 27, 27. T hese reversing levers 39, 39, are each pivotally connected by a connecting rod 40 with the lever positioning member or 33 at the opposlte ends of the lever 24, and each is nrmally retained in proper position by a. spring 41, Secured thereto and to the member 23b or any convenient support.

For positively acting upon the lever positioning members 33, 33a, at the proper time to cause them to vdepress the respective ends of the shifting lever 24, I have provided lever shifting disks 42 mounted upon and rotated by the shaft 11. These disks may be adjustedmpon .the shaft 11-v both longitudi vnally and circumferentially by means of screws 43. Each disk has' a roll 44 mounted thereon which, on rotation of the disk 42, will engage the upper face of thelever positioning member 33, or 33, when it is in proper position for said engagement, to depress one end of the lever 24 and its pintle supporting member 22'and thus also act to raisethe opposite end of the lever l24, its pintle support and pintle.

The trip members 30, 30, are shown, Fi

8, as depending rods with laterally bent en s carrying rolls 45, 45, the rods threaded near their upper ends and provided with nuts 46, 46, disposed, respectively, Figs. 2,- 8, above and below the ends of clamp members 47, 47. These members are secured about the necks 48, 48, of the sound -arms 49, 49, movably mounted in the two branches of the sound carrying tube 50.

Each trip member is so adjusted as to posit-ion on the neck 48 of the sound arm that it will trip the -lever .39 when its roll is pushed against the same by the traveling sound arm 49. This happens when the needle 51 of the sound box 52having completed the reproduction of the record, is fed laterally or across the record sufficiently far I 30 to 'cause the roll -45 to engage themember 30, and this result is accomplished very satisfactorily if the sound arm is quickly delected laterally by a distorted or sharply pitched portion 53 of the groove at the end of the groove 54.

For supporting each soundarm 49. above` and out of contact with its record or turntable when not in use or when the record is to be changed, I have provided, Figs. 2, 8, on the -upper end of the sound conveying 'tube 50 and adjacent each neck 47a cam track 55 on` which the clamp .47 slides as the sound arm is swung laterally to the right and away from the turntable, and this ca'm 55 'gradually raises the sound arm 49 and box 52 to'a convenient inoperative position.l

The sound tube 5,0, Fig. 1, is shown forked near its upper end,^one :arm leadlng to each 'sound arm 49. The' lower end of the sound tube is carried down through the table 1, ex-

tended laterally `and provided with a horn,

not shown, or if desired, with any suitable sound magnifying device 56, and by means of a wire 57 or other convenient arrangemade on the foregoing .described orother suitable machine, by substituting a record making` needle or yrecorder for the reproducer. The record 16 of the irst portion of the piece to be reproduced isA then placed upon, either turntable, for instance, the lefthand one, Fig. 1. The record is securedto 18 therefrom thrusting the .top of the pintle 17 therethrough and then screwing the nut o its pintle 17, see Fig-7 ,by removing the nut` f down securely thereon, locking the record between the nut and the fiange 19.

The record 16 containing the balance or next-section of the piece is placed in position in the same manner on the right-hand turn- The left-hand end ofthe lever 24 is l table. then depresseduntil the tooth 28 on the rear face thereof is engaged by the lever 27,`thus permitting the vpintle 17 to dro within the hollow `shaft 9 until the toot 21 onl the flange 19 engages the crown teeth 20 onthe upper end of the shaft 9.-

The lever positioning members. 33, 33, will be in the osition shown in Fig. 4, the right-hand en of lever 24, Fig, 3, supporting the right-hand pintle 17 with its record in raised or linoperative position, Fig. 1.v Both needles are placed at the beginning of the respective records, one record, the lefthand one, being in operative position and the other in 'inoperative position. The motor 12a or other source of power is now started and the turntablesl5, l5, thus put into operation by' means 'of the pulley 12 and common shaft-1l. y

As already stated, the record groove is preferably provided at its end with a' short lrelatively sharp lateral extenslbn 53. The

28 on the lever 24 approximately a'n instant before the needle 51 reaches the lateral extension 53 at the end of the record. The

roll 45 thereafter still moving laterally', will then engagethe 'lever 39 as soon as the record is finished and the needle enters the lateral extension 53, which causes a quick movementj of the roll 45 against said lever.

yWhen theroll 45 engages thelever 39'it then, by reason of the link 40 connecting the lever 39 with member 33a, causes said member 33a to be thrown to the left,- Fig. 4, into the path of the' roll 44 on the Fig. 4 righthand disk 42. If when said member 33a is thus thrown laterally, the yielding catch 34 thereon should happen to engage edgewise the roll 44,A .said member 34 will 'yield against the spring 37 until the roll has passed, 'beyond its plane, 'the..narrow -outerend of the member 33 permitting this when the catch 34 will be immediately thrown again into the path of the roll 44 vby said'spring 37. On its next revolutiornor its first revolution if said edgewise contact did not take place, the roll 44 will engage the upper face of the member 31 and depress the same with that end of the lever 2J( bringing the catch 28 thereon beneath the hooked end of the spring pressed lever 27, the spring 31 throwing the lever 27 forward and locking the lever 24 in that position.

Then that end of lever 21 is depressed the pintle supporting member 22 thereon is also depressed permitting the pintle 17 and record 16 locked thereto, hithertoin inoperative position to fall into operative position, the tooth 21 on the pintle 17 engaging the crown teeth 20, and imparting the motion of the Fig. 1, rotating right-hand turntable to the record 16.

By the same motion of the lever 24, the

left-.handlhitherto operative, record is withdrawn intoinoperative position by being raised by the rising left-hand'end of lever groove, the record is again ready to be automatically placed in operation by a repetition, in the reverse direction, of the fore going described operation of the trip member 30, actuated by the levers 27, 39, and shifting of lever 24, raising the right pintle and record and lowering again the lefthand pintle and record.

Obviously this operation of the talking machine may be continued Without any noticeable interruption of the reproduction of the record as long as desired, and completely overcoming the objectionable delays and interruptions hitherto occasioned by changing the records.

Obviously, by using recording Styli instead of reproducing styli, the foregoing embodiment of my invention may be used for recording sounds as Well as reproducing them, and many features of the invention, such as the successive operation in repeated cycles of the record carrying members would be as advantageous when the machine was so used.

'liile the above embodiment of my invention providesI a most satisfactory form of construction, it may be possible to vary the same in many respects within the spirit of the invention arid the scope ofthe lappended claims.
